Dinosaur Eggs are one of the many egg types in the Roblox game Grow a Garden. Unfortunately, Dinosaur Eggs aren't available in the game right now, but they may come back in a future update or event. If that happens, you'll want to be prepared—and this article can help you! In this wikiHow, we'll explain how Dinosaur Eggs were obtained, how to hatch them, and what pets you can obtain from them (plus their hatch rate and traits).

Dinosaur Eggs in Grow a Garden

Dinosaur Eggs were obtainable during the Prehistoric Event in July 2025. If you still have a Dinosaur Egg, you can hatch it by placing it in an empty spot in your garden. The egg will take just over 4 hours to hatch, and can contain a Raptor, Triceratops, Stegosaurus, Pterodactyl, Brontosaurus, or T-Rex.
